The invention relates to a method of rheologically casting and rolling an AZ91D magnesium alloy sheet with a rotating tube, belonging to the field of the metal casting. The method of rheologically casting and rolling the AZ91D magnesium alloy sheet with the rotating tube is characterized by comprising the following steps: melting AZ91D magnesium alloy in a melting furnace until the molten AZ91D magnesium alloy being 740-760 DEG C; adding C2Cl6 to the molten AZ91D magnesium alloy to modify the molten AZ91D magnesium alloy, reducing the temperature of the molten AZ91D magnesium alloy to 615-675DEG C; stirring the molten AZ91D magnesium alloy, scattering refining agent on the wave crest of the molten AZ91D magnesium alloy to refine the molten AZ91D magnesium alloy for 15-20 min, reducing thetemperature of the molten AZ91D magnesium alloy to 615-675 DEG C, and keeping the temperature of the molten AZ91D magnesium alloy at 710-730 DEG C; preheating a rotating pipe to 80-150 DEG C, controlling the angular speed of
